Answer:
0.55 m/s
Explanation:
Parameters given:
Mass of lighter car, m = 1400 kg
Mass of heavier car, M = 1850 kg
Initial speed of lighter car, u = -1.10 m/s (since it's moving to the left)
Initial speed of heavier car, U = 1.5 m/s
Final sped of heavier car, V = 0.25 m/s
Using the principle of conservation of momentum, total initial momentum is equal to total final momentum:
m*u + M*U = m*v + M*V
Inputting the values:
(1400 * -1.1) + (1850 * 1.5) = (1400 * v) + (1850 * 0.25)
-1540 + 2775 = 1400v + 462.5
1235 = 1400v + 462.5
1400v = 772.5
v = 772.5/1400
v = 0.55 m/s
Density is equal to mass divided by volume; that said, you would divide 38.6 by 2 to get your answer
Answer:
Explanation:
initial velocity(u) = 4 m/s
final velocity(v) = 13 m/s
acceleration(a) = 2m/s^2
time(t) = ?
v = u + at
13 = 4 + 2 × t
13 = 4 + 2t
2t = 13 - 4
2t = 9
t = 9/2
t = 4.5s
